Abstract
Collingwood's re-enactment doctrine, the notion that the historian must re-enact the past in his own mind, forms the methodological pillar of Collingwood's constructivism. The first tenet of this interpretation states that for the past to be knowable it must have left traces analyzable in the present. Second, the historical process must be rational, which necessitates that the object of knowledge be "re-enactable" and that the subject of knowledge (the historian) be "re-enact-capable." Third, both subject and object must come in contact in an actual act of knowing. Finally, criticism and justification of this reconstruction must constantly take place in order to assure that this reconstruction is actual. This interpretation was developed by Collingwood over several of his works. Our understanding of it is clarified by a study of his unpublished manuscripts, which have only recently been made accessible.
